ANSWERS: a) Equal

                    b) proportional


Similar Polygons

Similar polygons have the same shape, but can be different sizes. Specifically, two polygons are similar if two things are true:

  1. The corresponding sides of each are in the same proportion
  2. The corresponding interior angles are the same (congruent).

So when you take a square and compare it with another square, all sides of 1st one are proportional to another. And all angles are of course 90 degrees.
